It's worth knowing the tricks so you can see through them.

• The big number hook. The publisher leads with a massive TAM or CAGR to grab attention, then buries the caveats in the methodology section. You're meant to quote the headline, not read the footnotes.

• Layering unverified data. They cite a secondary source that itself cites an unknown primary source. The chain breaks, but it looks credible because there are citations.

• Using 'market size' loosely. Some reports measure the "vape market" by including adjacent products like herbal vaporizers or e-liquids for non-nicotine use. That inflates the number and muddies compliance relevance.

• Hiding the forecast model. They'll show you a pretty chart with historical data and projections blended on the same line, so it's hard to see where actuals end and guesses begin.

• The 'premium' pricing trick. A high price tag doesn't mean high quality. Some sellers charge thousands for reports that are essentially repackaged public data with a slick layout.

Your best defense is a skeptical eye and a checklist of green flags.
